CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
2. Introduction
• A heat pipe is a device that efficiently
transports thermal energy from its one point to
the other.
• It utilizes the latent heat of the vaporized
working fluid instead of the sensible heat.
• As a result, the effective thermal conductivity
may be several orders of magnitudes higher
than that of the good solid conductors.
6. Component of heat pipe
1.Container
• Metal Tubing, usually
copper or aluminum.
• Provides a medium
with high thermal
conductivity.
• Shape of tubing can be
bent or flattened.
7. 2.Working Fluid
• Pure liquids such as helium, water and liquid
silver
• Impure solutions cause deposits on the interior
of the heat pipe reducing its overall
performance.
• The type of liquid depends on the temperature
range of the application.

Examples of Working Fluid
12. Purpose of the Wick
• Transports working fluid from the Condenser to the
Evaporator.
• Provides liquid flow even against gravity.
13. How the Wick Works
• Liquid flows in a wick due to capillary action.
• Intermolecular forces between the wick and the fluid
are stronger than the forces within the fluid.
• A resultant increase in surface tension occurs.
14. Ideal Thermodynamic Cycle
• 1-2 Heat applied to evaporator through external sources
vaporizes working fluid to a saturated(2’) or superheated
(2) vapor.
• 2-3 Vapor pressure drives vapor through adiabatic
section to condenser.
• 3-4 Vapor condenses, releasing heat to a heat sink.• 4-1 Capillary pressure created by menisci in wick pumps
condensed fluid into evaporator section.
• Process starts over.
15. Heat Pipe Applications
• Electronics cooling- small high performance
components cause high heat fluxes and high heat
dissipation demands. Used to cool transistors and
high density semiconductors.
• Aerospace- cool satellite solar array, as well as
shuttle leading edge during reentry.
• Heat exchangers- power industries use heat pipe
heat exchangers as air heaters on boilers.
• Other applications- production tools, medicine and
human body temperature control, engines and
automotive industry.
20. Types of Heat Pipes
• Thermosyphon- gravity assisted wickless heat pipe.
Gravity is used to force the condensate back into the
evaporator. Therefore, condenser must be above the
evaporator in a gravity field.
• Leading edge- placed in the leading edge of
hypersonic vehicles to cool high heat fluxes near the
wing leading edge.
• Rotating and revolving- condensate returned to the
evaporator through centrifugal force. No capillary
wicks required. Used to cool turbine components and
armatures for electric motors.
• Cryogenic- low temperature heat pipe. Used to cool
optical instruments in space.
21. Advantages Of Heat Pipes
• Last a very long time.
• Completely noiseless.
• Requires no mechanical or electrical
input.
• Provide lower operating costs.
• Are virtually maintenance free.
• Are environmentally safe.
22. Disadvantages
• High cost.
• Requires that the air streams must be
relatively clean and may require filtration.
• Requires that the two air streams be adjacent
to each other,
23. CONCLUSION
• Heat pipe is a thermal super conductor under
certain heat transfer condition they can transfer
the heat energy 100 times more than available
best conductive materials, because of negligible
temp. Gradient exist in heat pipe.
• The heat pipe has compactness, light weight,
reversible in operation and high thermal flux
handling capability makes heat pipe to use new
modern era and in many wide variet application
to overcome critical heat dissipation problem.
